Sharper Image PowerBoost Circuit Massage Gun [2026 Version] Deep Tissue Percussion Massager with 6 Speeds for Back, Shoulders, & Full Body Muscle Pain Relief, with 4 Attachments & Travel Case

The Sharper Image PowerBoost Circuit is a full-size deep tissue percussion massage gun that combines serious muscle recovery performance with a design unlike anything else in the category. Chrome-plated transparent housing reveals the brushless motor and internal engineering, so you can see the precision behind every pulse. The shine-through LED readout displays speed and battery status directly through the housing — no separate screen, no stickers, just integrated design. Under the surface, the adaptive force brushless motor automatically increases percussion intensity when you press harder into muscle tissue and eases back when you lighten up. This means you control the depth of your massage with your hands, not just the speed dial. Six speed levels give you additional control, from a low setting suited for warming up or working sensitive areas like the lower back and shoulders, to a high setting built for dense muscle groups like glutes, hamstrings, and the upper back. Four interchangeable attachment heads are included for full-body coverage: a round ball head for large, flat muscle surfaces; a flat head for broad strokes across the back and chest; a fork head that tracks along both sides of the spine without pressing on bone; and a cone head for focused trigger point and knot work on smaller areas like calves, forearms, and feet. SafeLock+ attachment detection electronically verifies each head is locked in before the motor activates — an added safety step that prevents the gun from running with a loose or missing attachment. The angled ergonomic handle sets the Circuit apart from standard T-shape massage guns. The angle increases leverage and reduces wrist fatigue during extended sessions, especially when reaching your own back and shoulders. Combined with Quiet Drive low-noise technology and a soft-touch grip, the Circuit is comfortable to use for 10–15 minute recovery sessions without hand cramping or noise disruption. The Circuit runs on a USB-C rechargeable battery with up to 3 hours of cordless runtime per charge. The included carrying case stores the massage gun and all four attachment heads for organized transport between home, gym, and travel. What's in the box: PowerBoost Circuit Massage Gun, 4 interchangeable attachment heads (round, flat, fork, cone), USB-C charging cable, carrying case, and instruction manual.
